'Cast Out Demons' in the Bible

And if Satan also is divided against himself, how shall his kingdom stand? because ye say that I cast out demons by Beelzebub.

And if I by Beelzebub cast out demons, by whom do your sons cast them out? therefore shall they be your judges.

But if I by the finger of God cast out demons, then is the kingdom of God come upon you.

And he said unto them, Go and say to that fox, Behold, I cast out demons and perform cures to-day and to-morrow, and the third day I am perfected.
